Linear equations are any algebraic equations where both sides of the equation are polynomials or monomials of the first degree.
single-variable equations
Single-variable linear equations can always be expressed in the form:
where 
and 
are constants and 
is the variable.
From this form, they can be solved with the following steps:
1. subtract from both sides.
2. divide from both sides.
two-variable equations
Two-variable linear equations can always be expressed in the form:
Where 
and are variables and 
and are constants.
Two-variable linear equations can be drawn as a straight line on a coordinate plane.
can be defined as the slope and can be defined as the y-intercept
